Life-threatening waves expected at Lake Michigan beaches Monday: weather service

Life-threatening waves and currents are expected at Chicago beaches Monday, according to the National Weather Service.

Waves as high as 4 to 7 feet are expected at Lake Michigan beaches on the shoreline of Cook County, the weather service said in a “beach hazards warning.” Strong rip currents and structural currents are also expected.

Structural currents form along piers and can sweep swimmers into deeper water along the structure, the weather service said.

The warning lasts through the night, the weather service said. Anyone visiting beaches is advised to stay out of the water.

Last week, a man died after being found in Lake Michigan near Diversey Harbor.
